THE MORE SUBSTANTIAL BAND OF DEEP LAYERED CLOUDS WAS LOCATED WITHIN 200 MILES OF THE CURVE FROM 27N 180 TO 30N 175W AND FURTHER SOUTHWEST AND NORTHEAST. THE MORE BROKEN-UP BAND OF LOW TO MIDDLE CLOUD LAYERS AND STRATOCUMULUS FRAGMENTS WAS LOCATED WITHIN 60 MILES OF THE CURVE FROM 18N 180W TO 26N 172W TO 30N 158W AND FURTHER WEST AND NORTHEAST. HIGH AND LOW LAYERS OF THE NORTHERNMOST BAND MOVED IN OPPOSITE DIRECTIONS...WHILE THE SOUTHERNMOST BAND SHIFTED NORTHWEST SLOWLY. TO THE SOUTH...THERE WAS LITTLE THUNDERSTORM ACTIVITY TO MARK AN ITCZ. LAYERED LOW TO MIDDLE DEBRIS CLOUDS FROM EARLIER CONVECTION MOSTLY OBSCURED LOWER FEATURES BETWEEN 11N AND 01N. HOWEVER... ISOLATED THUNDERSTORMS ASSOCIATED WITH A TROUGH OF LOW PRESSURE DEVELOPED WITHIN 60 MILES OF THE POINT 08N 158W...AND THEIR DEEP LAYERED DEBRIS CLOUDS OBSCURED LOWER FEATURES WITHIN THE AREA BOUNDED BY THE CURVE FROM 13N 158W TO 09N 147W TO 04N 161W TO 07N 173W TO 13N 166W. MIDDLE TO HIGH CLOUD LAYERS FORMING IN ASSOCIATION WITH A WEAK TROUGH OF LOW PRESSURE IN THE MIDDLE ATMOSPHERE OBSCURED LOWER FEATURES NORTH OF THE CURVE FROM 30N 165W TO 19N 170W TO 25N 149W TO 20N 140W. LOWER IN THE ATMOSPHERE...A LAYER OF MARINE STRATUS MOVING IN FROM THE NORTHEAST BROKE UP INTO FRAGMENTS AND BANDS OF MARINE CUMULUS AND STRATOCUMULUS IN THE CORNER NORTH OF 13N AND EAST OF 166W. THESE CLOUDS GENERALLY MOVED TOWARD THE WEST SOUTHWEST AT 15 TO 20 MILES AN HOUR...AND ROSE TO HEIGHTS OF 6000 TO 9000 FEET...THOUGH A FEW TOWERING CUMULI ALONG THE SOUTHWEST EDGE OF THIS AREA APPROACHED 20000 FEET. ACROSS THE MAIN HAWAIIAN ISLANDS...HIGH TO MIDDLE CLOUD LAYERS OBSCURED LOWER FEATURES MOSTLY OVER KAUAI COUNTY...AND PARTLY OVER OAHU AND MOLOKAI. WHERE THEY WERE VISIBLE...LOWER CLOUDS CONSISTED ABOUT EQUALLY OF MARINE CUMULI AND STRATOCUMULI MOVING ASHORE ALONG SLOPES FACING EAST AND LAYERED DEBRIS CLOUDS FROM AFTERNOON CUMULUS BUILDUPS OVER HIGHER TERRAIN. BANDING IN THE STRATOCUMULI OVER OAHU PARALLEL TO THE KOOLAU RANGE IMPLIED THE PRESENCE OF TURBULENCE WITHIN THAT LAYER. AREAS WITH THE GREATEST CLOUD COVER INCLUDED EAST-CENTRAL KAUAI...NORTHEAST OAHU...THE WEST MAUI MOUNTAINS... NORTHWEST MIDDLE SLOPES OF HALEAKALA ON MAUI...AND MOST LOWER TO MIDDLE SLOPES OF THE BIG ISLAND EXCEPT IN THE KAU DESERT REGION. THESE LOWER CLOUDS GENERALLY ROSE TO HEIGHTS OF 5000 TO 7000 FEET. RADAR DATA FROM NEAR THE ISLANDS SHOWED SCATTERED SHOWERS OFFSHORE WELL TO THE SOUTHEAST OF THE BIG ISLAND...BUT ISOLATED SHOWERS AT MOST ELSEWHERE. $$ RYSHKO +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
